ISAAO NEWTON HOPKINS, OF LOOKPORT, ASSIGNOR TO MAROELLUS HARTLEY AND MALCOLM GRAHAM, OF NEW YORK, N. Y.

BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 550,507, dated November 26, 1895.

Application filed June 10, 1895.

To all whom it may concern:

Be it known that I, ISAAC NEWTON Hor- KINS, of Lockport, in the county of Niagara and State of New York, have invented a new and Improved Bicycle-Bell, of which the following is a full, clear, and exact description.

The object of my invention is to provide a bicycle-bell which may be applied to the machine without disfiguring it or offering any impediment to the free use of the handle-bar, while it affords sufficient volume of sound for practical purposes.

My invention consists in a combined bicycle handle and alarm-bell, which can be readily placed on the handle-bar instead of one of the ordinary handles, and which can be operated by the thumb of one hand.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of a handlebar with my improved bell attached. Fig. 2 is an enlarged longitudinal section of the bicycle handle and bell, and Fig. 3 is a longitudinal section of a modified form.

The handle A in the present case is made in tubular form, to fit on the handle-bar B, which may be of any well-known form. To the end of the handle is secured a metallic ring a, which is attached to or formed integrally with the U -shaped yoke 19, which supports the bell B, the yoke being provided with a threaded stud c and the bell being drilled and tapped to receive the said stud. The rim of the bell is supported near, but not in contact with, the outer end of the handle A, and the external form of the bell is such as to conform to the curvature of the handle, forming a finish forthe end of the handle.

The yoke b is provided with a lug d, supporting the stud e, on which is pivoted the boss f of the bell-hammer g. The boss f is provided with a projecting tooth h, against which rests the end of the rod *6, extending longitudinally through the handle. The boss f is provided with a shoulder j for tripping the rodt' after the bell-hammer has completed its back-stroke, and a curved spring 70, attached to the ring a, bears on the back of the Serial No. 552,330. (No model.)

hammer-arm and tends to throw the bellhammer forward after the tooth It has been released from the rod 2'.

To insure a clear stroke of the hammer on the bell, the arm of the hammer strikes a stud Z, projecting from the lug (Z, before the hammer completes its stroke, and at the completion of the stroke of the hammer the arm, being released, the spring of the hammer-arm causes the hammer immediately to withdraw from the bell without interfering with its vibrations. The rod 1' is by preference placed in a longitudinal groove formed in the inner surface of the tubular handle A, and the groove, with the rod inclosed, is covered by a strip m of thin metal, which prevents the cement used for attaching the handle to the handle-bar from interfering with the action of the rod 1'. point of starting after the bell-hammer has been operated by a looped spring 1', attached The rod 2' is returned to the at one end to the yoke b and having its other end connected with the rod 2'. The rod 01 at the inner end of the handleis turned outwardly approximately at right angles and provided with a thumb-piecen.

When the rod 2 is pushed toward the bell B, the engagement of the end of the rod with the tooth h of the boss f lifts the hammer g, and the further movement of the rod 1' causes the shoulder j to throw the end of the rod out of engagement with the tooth h when the spring is causes the hammer to strike the bell B.

In the modification shown in Fig. 3 the bell B, which is arranged as a vibrating bell, is attached to the handle A in the manner already described, and the bell-hammer is vibrated by means of a crank 0, carried by the pinion p, which receives its motion from a rack g on the rod '5. The crank 0 is connected by a rod 1' with a crank 8, attached to the bell-hammer arm. When-the rod "6 is pushed in, the pinion 19 is revolved, the crank 0 imparts a vibratory motion to the hammer and for each movement of the rod i several strokes are made upon the bell B by the hammer g. The rod 2' is returned to the point of starting by the looped spring 2', as in the other case. v

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, of a bicycle handle having a longitudinal passage formed therein, a bell support attached to the end of a handle, a bell carried by the bell support and furnished with a hammer, and a hammer-operating rod extending through the longitudinal passage of the handle and provided with a finger piece at the inner end of the handle, substantially as specified.

2. The combination with a bicycle handle, of a bell 011 the end of the handle, forming a tip or finish for the same, a pivoted hammer, a spring-pressed rod extending through the handle and provided with a finger piece at the inner end of the handle and mechanism connected with the rod and the hammer, for causing the hammer to swing on its pivot by the longitudinal movement of the rod, substantially as specified.

3. The combination with a bicycle handle, of a bell support projecting from the end of the handle, a bell secured to the outer end of the support and surrounding the same, a bell hammer provided with a boss having a tooth and mounted in the bell support, a spring engaging the hammer, and spring pressed operating rod extending through the handle and having its inner end engaging the tooth of the boss of the hammer substantially as described.
